Heat pump funding in Dundee
Multiple stacking incentives apply to commercial heat pump installations in Dundee in 2026.
100% first-year tax relief
Heat pump systems qualify as plant and machinery for Full Expensing — 100% of capex deducted from corporation tax in Year 1. A £150,000 heat pump installation delivers a £37,500 tax saving at 25% corporation tax. No cap, permanent, applies to all qualifying commercial heat pump types.
Interest-free loans for public sector
NHS trusts, schools, councils and universities in Dundee can access Salix BAU interest-free loans for heat pumps. Repaid from energy savings over 5–12 years. Open-ended and accepting applications now. PSDS Phase 4 closed November 2024 but Salix BAU continues — no end date.
Zero VAT with renewable system
Heat pumps installed as part of a renewable energy system (e.g. alongside solar PV) qualify for 0% VAT on supply and installation. Standalone commercial heat pump VAT eligibility depends on installation context — we assess qualification case-by-case to maximise VAT recovery.
Solar-powered heating at near-zero cost
A solar + heat pump system in Dundee uses daytime PV generation to power the heat pump compressor at near-zero marginal cost. Every 1 kWh of solar produces 3.5–5 kWh of useful heat (CoP 3.5–5.0). Particularly effective in Dundee buildings with continuous heating demand — hospitals, leisure centres, food production.
Heat pump types for Dundee commercial buildings
Most common commercial installation in Dundee. Extracts heat from outdoor air — effective down to -15°C with modern units. Low installation disruption. No ground works required. Suited to offices, retail, warehouses and healthcare buildings.
Higher CoP than ASHP, particularly in winter. Requires ground loop installation — open land or borehole drilling. Suited to Dundee sites with available land (rural fringe, business parks, hospitals). More capital-intensive but lower running costs.
Delivers flow temperatures up to 75°C — compatible with existing radiator systems without full fabric upgrades. Enables direct boiler replacement in Dundee older commercial buildings without refurbishment. Increasingly cost-competitive as grid and boiler gas prices diverge.
